VVith the foregoing and other objects in view, which will appear' as the description proceeds, my invention consists in the construction, arrangement and combination of parts of my apparatus wherehy the objects conternplated are attained, as hereinafter more fullyY set forth, pointed out in the appended claims, and illustrated in the accompanying drawings, in which Fig. 1, is a central cross sectional view of a wall heat register having an embodiment of the invention associated therewith;

Fig. 2, is a front elevational view of the same;

Fig. 3, is a central cross sectional view of a humidifier embodying the invention;

Fig. 4, is a front elevational view of the same, parts thereof being broken away; and

Figs. 5 and 6, are cross sectionai and front elevational views respectively of a modified form of the invention.

In the drawings, wherein for the purpose of illustration are shown the preferred embodiments of the invention, the numeral 10, designates a heat register of usual and well known construction. mounted in the usual manner in the wall 12, of a room, said register having the grating 11, which is positioned in an opening provided therefor in said wall 12, said opening communicating with the hot air fiue 13. In place of the usual hinged closure member provided in registers of this type for regulating the admission of heat to the room, I provide a humidifier gencrally designated by the reference character 14, said humidifier being pivotally hinged to the upper portion of the inner face of the grating 11, as shown at 15, by means of hinges 1G, or in any other suitable manner.

The humidifier 14, compriscs a liquid containing receptacle 18, of suhstantially right triangular cross section, the apex of the triangle being at the lower portion. and the hypotenuse thereof being the rear face of the receptacle. The front face 17 of the receptacle is disposed in a substantially Vertical plane, and is adapted to be moved to open and close the openings in the grating 11, for regulating the passage of heat through the register into the room. The receptacle 18., ma): be, if desired, fornied from a single sheet of material. such as brass. or the like, said reoeptacle being closed on all sidcs, by means of a seam 19, or the like, as shown in Fig. 3, said seam being made water tight for preventing lealiage of water therethrough. In the front face 17, near the upper portion thereof. a plurality of openings 20, for venting the Chamber 18, are provided. Also. a filling opening 21,

.through which the Chamber 18, may be iillerl through the openings in the grating 11, is provided in the front face 17, near the upper z portion thereof.

In order to cause a more rapid evaporation of the liquid in the humidifier, I provide on the frontface 17, thereof, an auxiliary liquid container 22, said container being relatively fiat and substantially rectangular in form, and of a size somewhat smaller than the size of the front face 17. The container 22, is constructed from a material possessing a high heat conductivity, such as copper or the like. and is open at the top for permitting the ready escape of vapor formed therein. In the form illustrated, the container 22, is rigidly and fixedly secured in spaced relation and parallel to the front face 17, in any well known and suitable manner, such as by solderin g the. four Corners of the container to the front face 17, as shown at 23. In order to estahlish communication between the auxiliary container and. the reccptacle 18` one or both of the lower soldered corners 23, may be bored to provide the passage 24, leading from the receptacle 18, to the hottom portion of the container, thus permitting the liquid in the Chamber 18, to fiow into and to rise to the same level in the container 22. One or both of the soldered upper Corners 23, may be bored to provide the passage 25, for providing an overflow opening from the container 22. into the receptacle 18, thus preventing the spilling over of liquid from the auxiliary container.

For the purpose of causing a more rapid evaporation of the liquid contained in vthe auxiliary container, I dispose within said container a. screening 26, of copper or the like, said screening completely filling the container. The action of the sereening will be readily understood by those skilled in the art. Said screening will not only separate the liquid into small particles which will be more readily evaporated, but will also tend to vibrate upon being heated, thus tending to cause a stirring up of the liquid particles, thereby causing a more rapid evaporation of the liquid. By spacing the container 22, from the front face 17, the said auxiliary container will be at allv times completely surrounded by the hot air passing through the fiue 13, thereby thoroughly heating the same.

An Operating handle 28, of suitable construction having means thereon for engagement with a. portion of the grating 11, is provided for holding` theI said humidifier in a plurality of positions. In the illustration shown in Fig. 1, the humidifier is held in position for closing the openings in the grating 11, thereby preventing the passage of heat from the hot air fiue 13, into the room through the register. Vhen it is desired to open the register the Operating handle 28, is actuated to move the humidifier about the hinges 1G, any desired amount, the said handle engaging a portion of the grating 11, for holding the said humidifier in the desired open position. It will thus be seen that the humidifier is not JlO ` mama? 'only adapted for moistening the air passing through the vregister into the room, but also acts as a closure means for regulat-ing the passage of heat into the room.

If desired, means may be provided for visibly indicating the level of vtlie liquid within the humidifier. In, the embodiinent illust-rated, the indicating ineans comprises a fioat meinber 80, of Cork, or any other material suitable for that purpose, said fioat member being mounted on one end of a rod 31, the other end of said rod 31, being rigidly secured to a transvei'se rod 82, intermediate the ends thereof, said rod 32, being mounted for pivotal movenient in tlie front and rear faces of the receptacle 18. The forward end of the rod 32, may be bent at right angles to provide the pointer 38, which pointer cooperates with designations marked on the front face 17. for visibly indicating the level of the liquid in the humidifier. The i'ear end of the rod 32, niay also be bent a slight amount to prevent the said rod from being displaced or inoved from its assembled operative position. lVhen the pointer 33, is opposite the designation marked F on the front face 17, the receptacle will be filled with a maximum amount of liquid, the level of which will be immediately below the passage 25, leading from the auXil-iary container to the receptacle 18, so as to prevent the overfiow of liquid through the top of the container 22.

It will thus be noted that I provide a humidifying means whicli is adapted for attachment to a wall heat register of the usual type, without altering the wall in which the regiister is located, said humidifying means also acting as a means for regulating the admission of heat into the room iii which the register is located. It will also be noted that by providing the auxiliary container a more rapid eva'poration of the liquid is obtained, thusL assuring a better and more eflicient moistening of the air. Also, the said humidifying means is so disposed when in assembled position with the register as to be entirely concealed from view from the iiiterior of the room containing the register.

In Figs. 5, and 6, of the drawings, a inodiiied form of the invention is illustrated. In

this form, the humidifier is construrted of a single piece of metal possessing` a high heat conductivity, such as copper, or the like, which is adapted to cause a rapid evaporation of the liquid contained therein. In the form illu'stratech the 'reference Character 40, designates generally a humidifier which may be 4 a'ttached to a wall' heat register of the usual type in a manner similar to that illustrated and `described in connection with the modification ill-ustrated in Figs. 3, and 4, The'de- `vice is hingedly secured to the register by means of the hinges 41, and is also provided with 'an Operating handle 2-8, similar to the me shown 'i-n Fig. 1, for o perati-n g the humidi- .fier to open and close the openings in the gratopenings in the grating 11. The receptacle is made out of a single sheet of material,

such as copper or the like, and is closed at the i'eai' by means of tlie seam shown at 44, which seam 'is made `water tight to prevent the lealzage of water therethrough. A slitted opening 45, extending substantially the full width of the receptacle near the upper portion thereof, is provided in the front face 48, said slitted .opening pi'oviding the means through which the said receptacle may .be .filled with i liquid, and also .through which the vapor formed in said receptacle may escape into the room for moistening the air therein.

If desii'ed, pockets for receiving `copper screening similar to that positioned in the auxiliary container 22, inay be provided On the sides of the receptacle 42, for causing a more rapid evaporation of the liquid contained therein.

It will thus be noted that the modified form" t of humidifier illusti'ated in Figs. 5, and 6, is simple, compact, neat in appearance, -easily and readily installed, and is adapted for attachment with a wall heat register of the usual type without `necessitating the altera-'`1| tion of the wa ll, and which Vwill be at all tiines practical and efficient for carfl'ying out the purpose for wliich it is designed.

lVhile the illustrated embodiments have been described with coiisderable particula1===v` ity, it is to be expressly understood lthat the invention is not to bo restricted to the particular form shown, as parts thereof a're capable of use' without other parts ,the-i'eof, as
